ui/phase-21: sciences CRUD list, designer, and production-picker integration

Lights up the player-defined sciences feature: a table view with sort
and filter, a designer with four percent inputs and a strict
sum-equals-100 gate, and a Research-sub-row integration so the
planet production picker lists the user's sciences alongside the
four tech buttons. Phase 21 decisions are baked back into ui/PLAN.md
(no UpdateScience on the wire — write-once via createScience +
removeScience; percentages instead of fractions; sciences live under
the existing Research segment).
